biostudies-literatureUnknown13(38)Watcharatpong TThe structure of the melt state of one-dimensional (1D) coordination polymer crystal Cu(isopropylimidazolate) (melting temperature <i>T</i> _m = 143 °C) was characterized by DSC, variable temperature PXRD, solid-state NMR (SSNMR), viscoelastic measurements, XAS, and DFT-AIMD calculations. These analyses suggested "coordination polymer-forming liquid" formation with preserved coordination bonds above <i>T</i> _m. Variable chain configurations and moderate cohesive interaction in adjacent chains are the keys to the rarely observed polymer-forming liquid. The melt structure is reminiscent of the common 1D organic polymer melts such as entanglement or random coil structures.Chemical science11422-11426https://www.ebi.ac.uk/biostudies/studies/S-EPMC9533396biostudies-literatureCoordination polymer-forming liquid Cu(2-isopropylimidazolate).PMC9533396Inoue THorike SOhara KMaihom TTabe HWatcharatpong TOgawa TWei YSKongpatpanich KKurihara TPila TfalseCoordination polymer-forming liquid Cu(2-isopropylimidazolate).The structure of the melt state of one-dimensional (1D) coordination polymer crystal Cu(isopropylimidazolate) (melting temperature <i>T</i> _m = 143 °C) was characterized by DSC, variable temperature PXRD, solid-state NMR (SSNMR), viscoelastic measurements, XAS, and DFT-AIMD calculations.
